Many cross-border taxpayers and business owners rush to file an incomplete return in April because they fear an IRS extension increases audit risk. In reality, filing Form 4868 is routine, automatic, and often prevents costly amended returns (Form 1040-X) later.
When Should You File an Extension?
- Foreign Tax Year Mismatch: India's financial year runs from April 1 to March 31, meaning final Form 16 and Form 26AS statements are often unavailable before the U.S. April 15 deadline.
- Pending Schedule K-1s or Corrected 1099s: Partnerships, S-Corps, and brokerage firms frequently issue K-1s or corrected 1099-B statements in late March or summer.
- First-Year Residency Election: Visa holders who arrive mid-year may need to wait until they satisfy the Substantial Presence Test later in the year to make a favorable First-Year Choice election.
